What is the function of the soft palate and uvula?
Function. During swallowing, the soft palate and the uvula move together to close off the nasopharynx, and prevent food from entering the nasal cavity. It has also been proposed that the abundant amount of thin saliva produced by the uvula serves to keep the throat well lubricated. It has a function in speech as well.

It is responsible for closing off the nasal passages during the act of swallowing, and also for closing off the airway. During sneezing, it protects the nasal passage by diverting a portion of the excreted substance to the mouth.

The function of the uvula is to block the nasal cavity when a person is eating or drinking. The soft palate comprises muscle and tissue, which make it mobile and flexible. When a person is swallowing or sucking, the soft palate completely separates the mouth from the throat, which helps keep food out of the respiratory tract.

While elevated, the soft palate creates a vacuum in ...

Is the soft palate flexible?
Unlike the bony hard palate, the soft palate is very flexible. It is composed of a strong, thin, fibrous sheet, known as the palatine aponeurosis, and the glossopalatine and pharyngopalatine muscles. A small projection called the uvula hangs free from the posterior of the soft palate.
What muscles attach to the soft palate?
Muscles of the soft palate – the tensor veli palatini (Figure 2) attaches to the scaphoid fossa and spine of the sphenoid and to the lateral surface of the cartilaginous portion of the auditory (Eustachian) tube. Its fibers descend between the lateral and medial pterygoid plates on the lateral aspect of the pharyngeal wall and give way to a tendon just above the pterygoid hamulus. The tendon hooks under the hamulus and turns medially to enter the soft palate, where it forms the palatine aponeurosis by fanning out and attaching to the posterior border of the hard palate. The palatine aponeurosis forms the basic structure of the soft palate to which other muscles gain attachment. Tensor veli palatini is supplied by the mandibular (V3) division of the trigeminal nerve and tenses the soft palate.
Which muscle is located in the soft palate?
The uvular muscle, also supplied by the pharyngeal plexus, lies entirely within the soft palate and elevates the uvula. In cases of unilateral paralysis of the soft palate, the uvula rises asymmetrically, being pulled away from the paralyzed side.
What is the name of the valve that narrows the opening from the nose into the throat?
A long palate narrows the opening from the nose into the throat. The excessive length of the soft palate and/or uvula acts as a noisy flutter valve during relaxed breathing.
What is the palate?
The palate forms the roof of the mouth and floor of the nasal cavity. The palate is divided anatomically into the bony hard palate anteriorly (part of the oral cavity) and the fleshy soft palate posteriorly (part of the oropharynx). The soft palate projects into the cavity of the pharynx from its attachment to the posterior edge of the hard palate. When elevated, it separates the oropharynx from the nasopharynx. Five paired muscles attach to the soft palate and contribute to its structure. In the midline the uvula projects downwards from its posterior free border.
Why is hypohyoid flap used?
Gangloff et al. 16) reported that hypo-hyoid myocutaneous flap was performed in order to reconstruct small or intermediate soft palate defects, and that its use was limited if patients had previously undergone thyroid surgery or radical neck dissection.
How to make your soft palate stiff?
The soft palate may be stiffened by inserting stiffening rods into the soft palate, or by injecting an irritating substance that causes stiffness in the injected area near the uvula.
Where is the palatoglossus located?
Palatoglossus descends from the inferior surface of the palatine aponeurosis and inclines slightly forwards to enter the posterolateral part of the tongue. The position of palatoglossus is evident on the inner surface of the oral cavity as a mucosal elevation, the palatoglossal ridge (anterior pillar of the fauces). The two palatoglossal ridges form the oropharyngeal isthmus, which marks the posterior boundary of the oral cavity. Innervated by fibers from the pharyngeal plexus, palatoglossus lowers the soft palate, raises the posterior part of the tongue and moves the palatoglossal ridge towards the midline, thus narrowing the isthmus.

Overview. The soft palate is located in the upper portion of the back of the mouth, behind the teeth. Soft palate cancer begins in the cells of the soft palate. Your soft palate is located on the upper portion of the back of your mouth, behind your teeth. Soft palate cancer is considered a type of throat cancer.
